4.3 update - bluetooth car functionality

Mav1 — Sat, 04 Jan 2014 10:37:15 GMT

Since updating my Z1 to 4.3 via the OTA update the integration to my car has become almost unuseable. the phone is recognised and the car can 'see' the network name. It also imports the contacts but not the call lists. Car controls are unuesable to control phone.

I can make a call if dialled from the phone, and the audio / mic works fine. I can't use the car controls to end the call.

This was all fine on android 4.2.something but it is not workingin 4.3 build 14.2.A.0.920 this is well documented across the web as being an issue withthe bluetooth stack and not a car needing an update / compatibility issue. please advise how quickly you can either:

1. issue a fix by updating . rolling back the bluetooth stack so it works correctly,

2. Tell me how i can roll back the OS on my phone to the previous version so i can continue using my phone with the car in a LEGAL way, until you or Google recognise, diagnose and resolve the issue.

Thanks,

Martin

Unfortunately we are unable to confirm specific date for any particular firmware release due to the nature of the approval process.. For further information regarding the approval process please see here.

Thanks Sam. ICS is old hat now. I would still like an answer to my question. How do I roll back to a version of jellybean (4.2.something) until the newer build of 4.3 is released that will hopefully fix the Bluetooth connectivity issue?

Oh, and 'you' certified the new build on 23rd December, per my link, so why is it taking do long to push out when so many people are reporting issues?

There are unfortunately no supported methods to roll back your firmware. If you would like a more updated explanation behind the update approval process please see here as this should answer you following question:

Thanks Sam. Disappointing I can't roll back and I'm stuck with a device that is unusable for long periods of time (when m in the car). Hopefully the new build of 4.3 will hit UK consumers and carriers soon.

try to connect via "throw".

I was noticing the same behaviour with my bt earphone, and i solved not only with the pairing, but also using "throw" for it.

Now when i connect, the throw blue icon comes out and the earphone works in correct way.

maybe can be related

I have the same problem with a Xperia ZL (C6506). Bluetooth car connectivity was working fine before the Android 4.3 upgrade (build version 10.4.B.0.569). I am using Sony PC Companion 2.1 to look for updates, but nothing is offered yet. Is there any chance to get a preliminary roll-out date? Or any proposal for a workaround?

It's pretty disappointing to have a high-end smartphone that is not usable in a car just because of a software upgrade, and there is apparently no way back to a working device for 4 weeks now ...

New build is out for the z1 c6903 but not on uk Vodafone, even by sony update service or PC companion. I believe the Bluetooth stack is fixed in the new release, just need Vodafone to approve it

Thanks for your quick response and the hint for the new release, Mav!

I feel I have not completely understood the approval process. I bought my Sony Xperia ZL without any simlock or branding, and use it with a German T-Mobile contract that I had already before.

Do I understand you correctly that each network provider - in my case T-Mobile - needs to approve the update before it will be made available via PC Companion?

Thanks again for your help, Markus

I think that is the case, but will vary by operator and counrty.

Its certainly the case in the UK

I have the same problem with my Opel Insignia's handsfree. Just to add that phone list is not uploaded in the car and that nothing is possible to control form the car system.

I am really surprised that Sony has not taken an urgent action or fix immediately.

AntonioRT - what software version have you got? 4.3? I had the same problems when I upgraded to 4.3 (.290 and .136) and I downgraded my phone back to 4.2.2 (.257) Works fine on that version. I dont think Sony will ever fix the problem.. Why should they? It will not sell more phones...

Nalab

Quickie question - with your 4.2.2 firmware is there within Settings > Xperia Connectivity a "Throw settings" option?

I think the Throw option may be incompatible with a number of Bluetooth stacks.

nalab1 — Tue, 04 Mar 2014 15:12:35 GMT

Yes, there is.. Its only got Auto-select Wireless Option and on my phone it is on (ticked)
